In the end I went for painting the regular camo, then a gloss varnish, followed by sprinkling salt on selected areas. Then I used a sponge to dab white acrylic paint on. I also gave it a sepia wash, quickly wiped off plus some weathering with Tamiya dry brushing products, particularly for the tracks.

The decals came last.

Not perfect either in the build or painting but I had fun and gained useful experience for my next try.
